Search for Life

A newfound exoplanet system with six sub-Neptunes has piqued the interest of scientists who seek extraterrestrial life.

Does life exist elsewhere in the universe? If so, how do scientists search for and identify it? Finding life beyond Earth is extremely difficult, partly because other planets are so far away and partly because we are not sure what to look for.

Organic material on Saturn moon Titan's surface may have difficulty getting to the underground ocean. That's where it'd need to go for Titan to potentially support life.

Astronomers revitalize an old concept called the SETI Ellipsoid that incorporates supernovas in the search for extraterrestrial intelligence.

Tests suggest the European Extremely Large Telescope will be able to detect crucial biosignatures on other worlds.

NASA has mounted all nine science instruments on its highly anticipated Europa Clipper spacecraft, which will launch toward Jupiter's icy ocean moon this year.

Space.com caught up with Bill Diamond, President and CEO of the SETI Institute for an exclusive, mind-stretching close-encounter discussion regarding the search for extraterrestrial intelligence.

A machine learning-based search for TESS data anomalies could lead us to proof of alien life.

A shallow soda lake in Canada could resemble Darwin's 'warm little ponds' found on the primordial Earth that had the right chemistry for life to get started.

Scientists are investigating the possible forms that alien languages might take — and whether we might be able to understand them.
